A stunning return to form by Christine Ohuruogu helped Britain achieve their
biggest medal haul in World Indoor Championship history as they won gold in
the 4x400 metres relay.

Ohuruogu has suffered badly with injuries and a loss of form since winning Olympic 400 metres gold in Beijing in 2008, and openly admitted she was not exactly keen on competing in Istanbul.

But the 27-year-old Londoner produced a storming third leg in the women's 4x400m relay, powering from third to first to set up hurdles specialist Perri Shakes-Drayton to anchor the team to gold by holding off individual 400m champion Sanya Richards-Ross of the United States.

"Training has been going well so I'm just happy that I've come out and we've won a gold medal," Ohuruogu said.

"I didn't really want to come here. I don't like indoors very much.

"It's been five or six months of winter training now so I'm happy that I could come here and finish my winter training in one piece with a successful run. I'm in a good place.

"I knew if I didn't run well, Lloyd (Cowan, her coach) was going to kill me anyway."

The gold was the highlight of a final day which brought five medals and took the team's tally to nine - surpassing the total of seven achieved in Birmingham in 2003 - with the men's relay quartet almost claiming gold as well when the USA were disqualified for a changeover infringement.

The team of Conrad Williams, Nigel Levine, Michael Bingham and Richard Buck eventually had to settle for silver when the American team's appeal was upheld, but that was added to bronze medals for Shara Proctor in the long jump, Andrew Osagie in the 800m and Holly Bleasdale in the pole vault.
